4 To all lwhom. it may concern:

Be it known that I, JOHN F. OCONNon, a citizen of the United States, residinv at Chicago, in the county of Cook and Stiate of Illinois, have invented a certain new and useful Improvement in vertically-Adjustable Side Bearings, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specifi- This invention relates to improvement in vertically adjustable side bearlngs.

One object of the invention is to provide a side bearing more particularly adapted 4for use on railwa cars and wherein are. em-

ployed a'nti-frlction elements such as rockers f 1n combination with means to change or adjust the effective height. of the bearing to pmpensate for different operating condi- Another object of the invention is to provide a side bearing of thecharacter above described wherein the vadjustment can be effected .without disturbing therelation of the anti-friction elements and the members immediately associated' therewith.

In the drawing forming a part of this specification, Figure 1 is a vertical lonfritudinal sectional view of a side bearing sliowing the same in position between the body and truck holsters of a car. And Figs. 2 and 3 are transverse vertical sectional views, taken'on the lines 2 -2 and 3 3, respectively, of Fig. 1.

VIn said drawing, 10 denotes the upper portion of a truck bolster to which the improved -side bearing is referably attached, and 11 indicates the un er portion of a bodv bolster, the holsters being movable in a well known manner.

The improved side bearing, as shown, comprises a base casting A, a pair of antifriction rockers B-B, a bearing cap C, a bearing plate D, and spring E for returning the arts to normal position.

Tiie base casting A comprises a lower wall 12 riveted to the truck bolster; a central 'upstanding extending rib or fiange 13 having an elongated horizontally extending slot 14; and side walls 15-15 at opposite sides of the central enlargement 1G from which the flange 13 extends. The upper surface of the lower wall 12, as will be understood, forms bearing surfaces for the under sides -teeth 19 formed on the base 'with the cap plate C. the cap plates are formed in pairs, two for 'each rocker B, as clearly indicated in Fig.

17 of the rockers B and to maintain the rockers in proper position at all times, the rockers are provided with. recesses 18 on their under faces with which coperate casting. The upper faces of the rockers B are provided with curved bearings, as indicated at 20,

which bearings' are concentric with the lower faces 17 of the rockers coperate with correspondingly convexly curved bearings 21-21 formed integrally The bearings 21 of 3, and separated by a recess 22 to provi the necessary clearance when the cap plate moves longitudinally over the vertical] extending fiange 13 of the base casting. 4 ach 0f the bearings 21 ofthe capplate is also made hollow, as indicated at 23, so as to v'accommodate oil and waste, indicated at 24, vto facllltate oilmg of the bearing. The waste 24 may be inserted through o enings 25 and the oil is adapted to feed to t ing surfaces through perforations 26.

The cap late C is provided on each side thereof witi a series of longitudinally extending ribs 27 with which cooperate correribs 28 formed on the inner faces of the dewill be obvious, by engaglng the ribs 27 and 28 in different positions, the height of the bearing late D can be varied and without disturblng the relation of' the rockers B with the baseA casting and cap plate. To retain the bearing plate D land cap plate C in an adjusted position, bolts 30 are employed, located as indicated most clearly in Fig. 1, said bolts being held by nuts 31.

To return the parts to normal position after each actuation, the spring E, which is mounted within the slot 14, has transversely extending spring followers 32-32 at its ends which followers bear against the ends of the slot in the flange 13 and said followers are also extended into suitable slots 33 in the depending side walls of the cap plate C, as clearly illustrated in Fig. 2. Hence, when the two holsters move relatively to each other and pressure is brought to bear on the bearing plate D, it is obvious that the plates D and C will be shifted longitudinally and the rockers B and are adapted to.

e rocker bearsponding series of longitudinally extending oscillated. This movement @den eause one of the followers 32 to move tos ward the opposite follower and compress the spring E. Upon removal of the pressure on the bearing, the spring E expands and forces the followers 32 apart to their normal position, which thereby returns the 'rockers and plates C and D to normal position.

Each of the rockers B is also centrally recessed', as indicated at 35, to clear the central vertical web 13 in the 'rockihi'mo'i'ement. Each of the spring followers 32 is provided with a cup 36 in which arey seated the ends of the spring E t'o prevent'the' latter from'becoming "displaced. 'A'
